Answer:
The gradualism model depicts evolution as a slow steady process in which organisms change and develop slowly over time. In contrast, the punctuated equilibrium model depicts evolution as long periods of no evolutionary change followed by rapid periods of change.
Explanation:
Chyme is actually produced both in the stomach and the small and large intestines of the digestive tract. This thick semifluid mass or digestive juice is responsible for breaking down the food and making it easily passable into the intestinal walls. Chyme is also responsible in preventing the gastric juices of the stomach to attach its own and within the intestines it breaks down food into proteins, starches, and fibers.
<span>Stabilizing selection operates when individuals within a population of average body size have more offspring than those of large or small body size. this is the worlds way of stabilizing the population to a safe average.</span>
When they reach size limitations....they divide by binary fission or any other process of reproduction !
second may be they stop division and stay at their state as happens in ovum of the female as they stops in diakinesis !!!
Answer:
Energy in an ecosystem is mainly made by the producers of an ecosystem. The net primary productivity in an ecosystem depends on many factors. Some of them are:
- Amount of sunlight: The amount of sunlight that the plants and trees might be has basic influence on the primary productivity. Plants and trees receiving enough sun light will be able to make more food for organisms living in that area as compared to the producers which do not receive enough sun light.
- Soil texture: The soil texture and the availability of nutrients heavily influence the primary productivity of an ecosystem. An area having a soil texture with not enough nutrients will not be able to grow more plants. As a result, the productivity would decrease.
